You can see how to manually update WordPress [here](https://www.greengeeks.com/tutorials/how-to-use-ftp-to-manually-update-wordpress/). * Best regards Aris Kuckovic * Thread Starter [skolaprachen](https://wordpress.org/support/users/skolaprachen/) * (@skolaprachen) * [2 years, 9 months ago](https://wordpress.org/support/topic/php-upgrade-14/#post-17044343) * Thanks for your reply, I did what you recomanded – even though I already apdated word press before changing PhP versin. * It is the same … the Fatal error note did not change :(. * May it be something wrong with the file script- loader? * function wp_default_packages( $scripts ) { wp_default_packages_vendor( $scripts); wp_register_development_scripts( $scripts );wp_register_tinymce_scripts( $scripts); wp_default_packages_scripts( $scripts ); * ```wp-block-code if ( did_action( 'init' ) ) { wp_default_packages_inline_scripts( $scripts ); } ``` * } * This is what is described as a fatall error – is there anything I can change about it? * [kuckovic](https://wordpress.org/support/users/kuckovic/) * (@kuckovic) * [2 years, 9 months ago](https://wordpress.org/support/topic/php-upgrade-14/#post-17044417) * [@skolaprachen](https://wordpress.org/support/users/skolaprachen/) * Hmm – I would never change any core-files in WordPress. Whenever I encountered an error in the “wp_admin” og “wp_includes” folder, it was solved by deleting the 2 folders from the FTP server, and reuploading them. * [kayconseil](https://wordpress.org/support/users/kayconseil/) * (@kayconseil) * [2 years, 9 months ago](https://wordpress.org/support/topic/php-upgrade-14/#post-17044547) * Bonjour, je suis dans la même situation que vous [@skolaprachen](https://wordpress.org/support/users/skolaprachen/). * Actuellement, j’essaie de passer de PHP 7.4 à PHP 8.0. * Dans mon cas, j’ai bien la dernière version WP, mes plugins sont à jour et j’ai désactivé le plugin non compatible avec la version PHP 8. * Pour vérifier la compatibilité de vos plugins à la version PHP en question, vous pouvez installer PHP compatibility Checker. * Le problème vient de mon thème qui n’est pas mis à jour par l’éditeur depuis 2022. Du coup, j’ai envoyé une demande à l’assistance technique de mon thème en question ; Son retour : il va vérifier la compatibilité du thème avec la dernière version de WP et une mise à jour sortira prochainement. À suivre… * Thread Starter [skolaprachen](https://wordpress.org/support/users/skolaprachen/) * (@skolaprachen) * [2 years, 9 months ago](https://wordpress.org/support/topic/php-upgrade-14/#post-17044588) * Merci pour votre message, en fait, j’ai finalement réussi à résoudre le problème– l’erreur venait en réalité du fait que je n’avais pas mis à jour tous les thèmes. J’ai dû revenir à la version PHP 7 et tout mettre à jour directement dans WordPress. Et cela, même si j’avais vérifié que tout était compatible avec PHP à l’aide de PHP Compatibility Checker. Bonne chance ! * BTW – I canť speak french– fortunately AI made a translation of my answer – hope it is undersatndeble. 🙂 * [kayconseil](https://wordpress.org/support/users/kayconseil/) * (@kayconseil) * [2 years, 9 months ago](https://wordpress.org/support/topic/php-upgrade-14/#post-17044638) * Thanks for your french feedback 🙂 AI, a good idea for the translation!
